from_list(list) 点击以切换源代码
将 [名称, 版本, 平台] 的数组转换为 NameTuple
对象的数组。
# File rubygems/name_tuple.rb, line 24 def self.from_list(list) list.map {|t| new(*t) } end
new(name, version, platform=Gem::Platform::RUBY) 点击以切换源代码
# File rubygems/name_tuple.rb, line 9 def initialize(name, version, platform=Gem::Platform::RUBY) @name = name @version = version platform &&= platform.to_s platform = Gem::Platform::RUBY if !platform || platform.empty? @platform = platform end
null() 点击以切换源代码
一个空的 NameTuple
,即 name=nil, version=0
# File rubygems/name_tuple.rb, line 39 def self.null new nil, Gem::Version.new(0), nil end
to_basic(list) 点击以切换源代码
将 NameTuple
对象的数组转换回
- 名称, 版本, 平台
-
的元组数组。
# File rubygems/name_tuple.rb, line 32 def self.to_basic(list) list.map(&:to_a) end

<=>(other) 点击以切换源代码
# File rubygems/name_tuple.rb, line 90 def <=>(other) [@name, @version, Gem::Platform.sort_priority(@platform)] <=> [other.name, other.version, Gem::Platform.sort_priority(other.platform)] end
==(other) 点击以切换源代码
与 other
进行比较。支持另一个 NameTuple
或 [name, version, platform] 格式的数组。
# File rubygems/name_tuple.rb, line 101 def ==(other) case other when self.class @name == other.name && @version == other.version && @platform == other.platform when Array to_a == other else false end end
也别名为:eql?
full_name() 点击以切换源代码
返回此 Gem
的完整名称(名称-版本)。如果不是默认的 Ruby 平台,则包含平台信息。这模仿了 Gem::Specification#full_name
的行为。
# File rubygems/name_tuple.rb, line 48 def full_name case @platform when nil, "", Gem::Platform::RUBY "#{@name}-#{@version}" else "#{@name}-#{@version}-#{@platform}" end end
hash() 点击以切换源代码
# File rubygems/name_tuple.rb, line 116 def hash to_a.hash end
match_platform?() 点击以切换源代码
指示此 NameTuple
是否与当前平台匹配。
# File rubygems/name_tuple.rb, line 60 def match_platform? Gem::Platform.match_gem? @platform, @name end
prerelease?() 点击以切换源代码
指示此 NameTuple
是否为预发布版本。
# File rubygems/name_tuple.rb, line 66 def prerelease? @version.prerelease? end
spec_name() 点击以切换源代码
返回 gemspec 文件将使用的名称
# File rubygems/name_tuple.rb, line 73 def spec_name "#{full_name}.gemspec" end
to_a() 点击以切换源代码
转换回 [name, version, platform] 元组
# File rubygems/name_tuple.rb, line 80 def to_a [@name, @version, @platform] end
